摘要
溶洞、岩体破碎带、岩体裂隙等不良地质极易引发突水突泥、坍方等重大灾害,并造成严重的经济损失和人员伤亡。在隧道施工过程中,采用探地雷达检测衬砌壁后空洞,并进行钻孔取芯验证,结果表明探地雷达用于壁后空洞检测可行且具有较高的可信度。
The geological conditions that need to be faced in tunnel construction are becoming more and more complex.Poor geology such as karst caves,rock fractured zones and rock mass fissures can easily cause major disasters such as water inrush,mud inrush and collapse,and cause serious economic losses and casualties.Ground penetrating radar(GPR)is used to detect the cavity behind the lining wall in the course of tunnel construction,and borehole coring is carried out to verify it.The results show that the application of GPR in the detection of the cavity behind the lining wall is feasible and has high reliability.
